This folder holds WebView's gpu-specific code.
WebView's gpu code always runs in the browser process.
Like with other content embedders, //android_webview/gpu/
can depend on //android_webview/common/
but not //android_webview/browser/
. It can also depend on content layer (and lower layers) as other embedders would (ex. can depend on //content/public/gpu/
, //content/public/common/
).
